Abstract
A bag having an integrally formed closure, comprising a wall, an opening contiguous to the wall, two handles attached to the wall at the opening, and a closure integrally formed in the wall of the bag adjacent one of the handles. The closure is formed of planar, resiliently flexible plastic in a circular shape with a rim and with multiple symmetrical radial cuts extending from the center of the closure to the rim, thus forming prongs that resiliently flex up and down from the center of the closure. This flexing forms an opening through the closure as long as one or more of the prongs are flexed.

- The above-referenced patent documents disclose various types of closures for bags. At least one of these patent documents discloses a vertical slit through both sides of a bag for closing the bag. However, none of the patent documents discloses a bag having a closure integrally formed in the bag. An object of the present invention is to provide a bag with an integrally formed closure.
- The Bag with Integrally Formed Closure of the present invention comprises a bag having a wall, an opening, two handles attached to the wall at the opening, and a closure integrally formed in the wall of the bag adjacent one of the handles. The closure is formed of planar, resiliently flexible plastic having a substantially circular shape. The closure has a rim slightly thicker than the rest of the closure. The closure also has multiple symmetrical radial cuts extending from the center of the closure to the rim, thus forming prongs that resiliently flex up and down from the center of the closure. This flexing forms an opening through the closure as long as one or more of the prongs are flexed.
- With the closure integrally formed in the wall of the bag adjacent one of the handles, the other handle can be pushed through from the inward side of the closure so that said other handle passes through the closure. The handle can then be further pulled through the closure from the outward side of the closure, until the handle has been drawn through the closure such that the bag is thereby closed for securing the contents in the bag for carrying. The resiliency of the prongs grasps and retains the handle in the closure. The closed bag can then be carried by either or both handles. The capturing of the handle by the closure prevents the contents of the bag from spilling out of the closed bag.
- The novel features of this invention, as well as the invention itself, both as to its structure and its operation, will be best understood from the accompanying drawings, taken in conjunction with the accompanying description, in which reference characters refer to similar parts, and in which:
-
FIG. 1 is a side view of the Bag with Integrally Formed Closure of the present invention, showing one of the handles of the bag drawn through the closure in order to close the opening of the bag; -
FIG. 2 is a detail view of the closure integrally formed in the side of the bag, showing the radial cuts in the planar plastic which form the resiliently flexible prongs of the closure; -
FIG. 3 is a cross-sectional view taken across line 3-3 ofFIG. 2 of the detail of the closure integrally formed in the side of the bag, showing the rim of the closure and one of the cuts in the plastic; and -
FIG. 4 is a cross-sectional view taken across line 5-5 ofFIG. 1 , showing the flexing of the prongs in response to the handle being pushed through the closure. - Referring initially to
FIG. 1 , the Bag with Integrally Formed Closure of the present invention is generally designated 100.Bag 100 has awall 102; anopening 104 contiguous towall 102; afirst handle 106 attached to wall 102 at opening 104; asecond handle 108 attached to the portion ofwall 102 adjacent the portion ofopening 104 opposite the portion ofopening 104 adjacentfirst handle 106; and aclosure 110 integrally formed inwall 102 adjacentsecond handle 108. The closure is formed of planar, resiliently flexible plastic in a substantially circular shape.Closure 110 has arim 111 slightly thicker than the rest ofclosure 110.Rim 111 strengthens bothclosure 110 and the portion of thebag 100 immediately surroundingclosure 110.Closure 110 has multiple symmetricalradial cuts 112 extending from thecenter 114 ofclosure 110 torim 111, thus formingprongs 120 that resiliently flex up and down from thecenter 114 ofclosure 110. This flexing forms an opening 124 throughclosure 110 as long as one ormore prongs 120 are flexed. -
Closure 110 can be integrally formed inbag 100 by havingclosure 110 molded withbag 100. Alternatively,closure 110 may be formed separately frombag 100,bag 100 may be formed with a circular hole a little smaller thanclosure 110, and rim 111 ofclosure 110 may be bound to the portion of thewall 102 surrounding the circular hole by means for fasteningclosure 110 to said portion ofwall 102. The means for fastening can include heat sealing, adhesive, stitching, or any other means for fastening of suitable strength. - With
closure 110 integrally formed inwall 102 adjacentsecond handle 108,first handle 106 can be pushed through from theinward side 130 ofclosure 110 so thatfirst handle 106 passes throughclosure 110. First handle 106 can then be further pulled throughclosure 110 from theoutward side 140 ofclosure 110, untilfirst handle 106 has been drawn throughclosure 110 such thatbag 100 is thereby closed for securing contents in thebag 100 for carrying. The resiliency ofprongs 120 retainsfirst handle 106 inclosure 110, thus keepingbag 100 closed. Theclosed bag 100 can then be carried by either or both ofhandles -
Bag 100 may alternatively be formed with onlyfirst handle 106 and withoutsecond handle 108. In this alternative embodiment,closure 110 is in the portion ofwall 102 adjacent a first portion ofopening 104 that is opposite a second portion ofopening 104 adjacentfirst handle 106. To use this embodiment,first handle 106 is pushed throughclosure 110 from theinward side 130 ofclosure 110 so thatfirst handle 106 passes throughclosure 110. First handle 106 can then be further pulled throughclosure 110 from theoutward side 140 ofclosure 110, untilfirst handle 106 has been drawn throughclosure 110 such thatbag 100 is thereby closed for securing contents in thebag 100 for carrying. The resiliency of theprongs 120 retainsfirst handle 106 in theclosure 110, thus keepingbag 100 closed. Theclosed bag 100 can then be carried byfirst handle 106. -
FIG. 2 shows a detail view ofclosure 110 integrally formed inwall 102 ofbag 100, showingradial cuts 112 in the planar plastic which form the resilientlyflexible prongs 120 ofclosure 110. -
FIG. 3 shows a cross-sectional view taken across line 3-3 ofFIG. 2 of the detail of theclosure 110 integrally formed inwall 102 ofbag 100, showingrim 111 ofclosure 110 and one of thecuts 112 in the plastic.FIG. 3 shows the portion ofwall 102 aroundclosure 110, integrally formed withrim 111 ofclosure 110. Alternatively, rim 111 can be fastened to either the inside or the outside ofwall 102. -
FIG. 4 shows a cross-sectional view taken across line 5-5 ofFIG. 1 , showing the flexing ofprongs 120 in response tofirst handle 106 being pushed throughclosure 110. The resiliency ofprongs 120 causes them to press againstfirst handle 106, which retainsfirst handle 106 inclosure 110, thus keepingbag 100 closed. - While the Bag with Integrally Formed Closure of the present invention as herein shown and disclosed in detail is fully capable of obtaining the objects and providing the advantages herein before stated, it is to be understood that it is merely illustrative of preferred embodiments of the invention and that no limitations are intended to the details of construction or design herein shown other than as described in the appended claims.
